Final answer:
To find the next terms, we add 6 to each previous term in the given sequence: 9, 15, 21, 48.
Step-by-step explanation:
To find the pattern and determine the next three terms, we need to examine the given sequence: 9, 15, 21, 48.
Looking at the sequence, we can observe that each term is obtained by adding 6 to the previous term. For example, 9 + 6 = 15, 15 + 6 = 21, and 21 + 6 = 27.
Therefore, the next three terms would be 27, 33, and 39.
